过氧化氢（H2O2）不仅是一种用途广泛的清洁强氧化剂，而且是一种很有前途的燃料电池燃料。摘要本文研究了负载金纳米粒子（NP）的金属氧化物（Au/MOs）作为光催化剂，通过电子-氧还原反应（2e—ORR）制备h2o2。基础部分讨论了h2o2合成的一般要求，Au NPs对2e -ORR的电催化活性，Au/MOs在黑暗和光照下Au NP的费米能级控制，以及控制h2o2生成催化活性的因素。随后，描述了在常温常压可见光照射下，水与o2的人工光合作用。最后，对结论进行了总结，并对今后的研究热点提出了方向。
Hydrogen peroxide (H2O2) is not only a versatile clean and strong oxidant but also a promising fuel for fuel cells. This Feature Article has shown that gold nanoparticle (NP)-loaded metal oxides (Au/MOs) can be promising photocatalysts for H2O2production via two electron-oxygen reduction reaction (2e–-ORR). The fundamental parts deal with the general requirements for the H2O2synthesis, electrocatalytic activity of Au NPs for 2e–-ORR, Fermi level control of the Au NP of Au/MOs in the dark and under light irradiation, and the factors for governing the catalytic activity for H2O2production. Subsequently, an artificial photosynthesis of H2O2from water and O2under visible light irradiation at ambient temperature and pressure is described. Finally, the conclusions are summarized with a direction of the future research on the hot topics.
